E. Zackrisson, P. Calissendorff, S. Asadi +1
If advanced extraterrestrial civilizations choose to construct vast numbers of Dyson spheres to harvest radiation energy, this could affect the characteristics of their host galaxi…
Metallicity at the explosion sites of interacting transients
F. Taddia, J. Sollerman, C. Fremling +8
Context. Some circumstellar-interacting (CSI) supernovae (SNe) are produced by the explosions of massive stars that have lost mass shortly before the SN explosion. There is evidenc…
No trace of a single-degenerate companion in late spectra of SNe 2011fe and 2014J
